Agus Nyohadi, 2008. The Influence of Using Some Commercial Concentrate Crude Protein 36 Percent to The Egg Weight, Feed Efficiency, and Income Over Feed Cost (IOFC)at Layer.
The research was held at June 14th to Juli 14th 2007 in Bacem village, Sutojayan District, Blitar City. The purposes of the research to know influences of using some concentrate crude protein 36 percent to The Egg Weight, Feed Efficiency, and Income Over Feed Cost (IOFC) at Layer period.
The materials used are 200 hens layer period which had 56 weeks old with Isa Brown strain CP 909 brand. The method of this research used Completely Randomization Design (CRD) with 5 treatment concentrate K1 (124-P), K2 (KLKS-36), K3 (Con 4-K), K4 (AS 204-36), K5 (KSL-36). Every treatment 4 repeating and every repeating by 20 hens. The feed which giving are combination bran, corn, concentrate crude protein 36 percent and minerals with 18 percent isoprotein in nutrient feed.
The result of analyzing variant shows not significant (P>0.05) to The Egg Weight, Feed Efficiency, and Income Over Feed Cost (IOFC) at Layer period.
The conclusion from result of this research shows that the using of some commercial concentrate crude protein 36 percent not significant (P<0.05) to to The Egg Weight, Feed Efficiency, and Income Over Feed Cost (IOFC) at Layer. Suggested in self mixing use commercial concentrate, user must.
